Parameters estimation of dynamic model of synchronous generators is an essential prerequisite for viable and reliable power system operation and offline studies. Advent of phasor measurement units (PMU) and its growing applications in power systems have led to an evolution in the electric power network wide-area monitoring, protection, and control. Alongside, these devices have revealed unprece...
This paper reports the design, fabrication, and testing of a soft electroactive polymer power generator that has a volume of 1cm. The generator provides an opportunity to harvest energy from environmental sources to power wireless sensor networks because it can harvest from low frequency motions, is compact, and lightweight. Electroactive polymers are highly stretchable variable capacitors. Ele...
BACKGROUND Nasal CPAP is widely used in neonatal ICUs. Aerosolized medications such as inhaled steroids and β agonists are commonly administered in-line through nasal CPAP, especially to infants with bronchopulmonary dysplasia. We hypothesized that aerosol delivery to the lungs via variable-flow nasal CPAP in an in vitro model would be unreliable, and that the delivery would depend on the posit...
Let A be the generator of a (C„) contraction semigroup on a Banach space. Let B be a dissipative operator with densely defined adjoint. Assume that the inequality H&cj|^|M:r|| + holds on the domain of A. Then the closure of /f + B generates a (C0) contraction semigroup. Let A be the generator of a (C0) contraction semigroup on a Banach space X. Let B be a dissipative operator on X in the sense ...
Center for Adaptive Systems and Department of Cognitive and Neural Systems Boston University, 111 Cummington Street, Boston, MA 02215 A four-channel neural pattern generator is described in which both the frequency and the relative phase of oscillations are controlled by a scalar arousal or GO signal. The generator is used to simulate quadruped gaits; in particular, rapid transitions are simula...
case presentation in this report, we describe a case of a cied infection in a 49-year-old female, admitted in 2013 to a hospital in copenhagen, denmark, with persistent staphylococcus epidermidis bacteremia without any clinical signs of generator-pocket infection and several negative tee studies. conclusions the diagnosis of cied infection was established with fluorodeoxyglucose positron emissi...
A reliable and accurate diagnosis of inter-turn short circuit faults is a challenging problem in the area of fault diagnosis of electrical machines. The purpose of this challenge is to be more efficient in fault detection and to provide a reliable method with low-cost sensors and simple numerical algorithms which not only detect the occurrence of the fault, but also locate its position in the w...
In recent years, microturbines as one the distributed generation sources have widly used. This paper investigates the control structure of the microturbine and analyzes its performance in grid-connected mode. In this way, first, the mechanical model of the microturbine is presented. Then, the electrical structure of the microturbine, consisting of permanent magnet synchronous generator (PMSG) ...
the objective of this study was to compare an indirect elisa, based on a purified 60 kda envelope glycoprotein (gp51su), with a pourquire indirect elisa for the detection of antibodies to the bovine leukemia virus. for conducting this research, 340 serum samples were collected from two different breeds of cows (sarabi and holestin) in different herds. commercial elisa revealed positive results ...
abstract in this paper, we study the generalized order- jacobsthal sequences modulo for and the generalized order-k jacobsthal-padovan sequence modulo for . also, we define the generalized order-k jacobsthal orbit of a k-generator group for and the generalized order-k jacobsthal-padovan orbit a k-generator group for . furthermore, we obtain the lengths of the periods of the generalized order-3 ...
